Abstract
An audio/visual alarm system which includes multiple microprocessor-controlled alarm units connected in a common loop to a fire alarm control panel and an interface control circuit. The interface control circuit causes brief interruptions in power to the alarm units which synchronize operation of the alarm units and which can also be used as alarm control signals. The interface control circuit allows for control of both audio and visual alarms using only the single common loop connection between alarm units.
